Why Limescale Builds Up (and Why It Matters)

If you live in a hard water area, limescale is basically a fact of life. It's the chalky white or grey crust that forms when water evaporates and leaves calcium carbonate deposits behind. It clogs showerheads, dulls taps, and left long enough, it can genuinely reduce water flow and damage your fixtures.

The good news? You almost certainly have everything you need to fix it already.

What You Will Need

Pick one of these: white vinegar, fresh lemon juice, or citric acid powder (you can get a 500g bag for around three pounds on Amazon — this is honestly the most effective of the three and lasts ages). You'll also need an old toothbrush, some elastic bands or string, and a cloth.

How to Descale Your Showerhead

Removable Showerheads

Unscrew the head and drop it directly into a bowl of undiluted white vinegar or a strong citric acid solution (two tablespoons to 500ml of warm water). Let it soak for at least an hour — overnight is better if it's heavily scaled. Then scrub with the toothbrush, paying attention to the individual nozzle holes. Rinse well and reattach. If the nozzles are silicone rubber, you can rub each one with your finger while rinsing and they'll pop clear instantly.

Fixed Showerheads

Pour vinegar or your citric acid solution into a plastic bag — a sandwich bag works fine. Submerge the showerhead in it and secure the bag tightly with elastic bands so the head is fully immersed. Leave for 30 to 60 minutes, then remove, scrub, and flush by running the shower on full for 30 seconds.

How to Remove Limescale from Taps

Soak a cloth in vinegar, wrap it around the tap, and secure it with an elastic band. Leave it for an hour. For stubborn buildup, cut a lemon in half and press it directly onto the end of the tap. Leave for another 30 to 60 minutes, then wipe off and buff dry. The key thing most people miss: always dry taps after wiping them. Even a quick wipe after each use slows limescale formation dramatically.

Citric Acid: the Upgrade Worth Making

Vinegar works, but the smell is unpleasant and it's not quite as effective as citric acid on heavy scale. Citric acid is odourless, cheap, and dissolves calcium deposits faster. Mix two to three tablespoons in 500ml of warm water and use it exactly the same way as vinegar.

How Often Should You Descale?

In a hard water area, monthly is ideal for showerheads. Taps can go every six to eight weeks. If you're in a soft water area, quarterly is fine.

FAQ

Does vinegar damage chrome taps?

Short-term exposure of an hour or two is fine for chrome. Don't leave acid on chrome overnight — it can dull the finish. Always rinse thoroughly.

Can I use bleach to remove limescale?

No. Bleach disinfects but it doesn't dissolve mineral deposits. You need an acid for that. Mixing bleach and vinegar also creates harmful chlorine gas.
